SELECTING A COMPOUND MICROSCOPE is as easy as 1-2-3...

Select the type of microscope you need or your industry

Select by type of microscope - Our Compound Microscope Assortment has been divided into major categories to make your shopping easy.

These categories include:

Brightfield, Darkfield, Phase-Contrast, Inverted and others

Choose a business application or industry to find the right compound microscope. Major industries or applicatins include:

Veterinary, Laboratory Use, Teaching, Metallurgical, Gemology and many others

Select a Magnification

AmScope offers an industry-leading selection of magnifications. All products are in-stock and usually ship the same day ordered

Select a Camera

We offer a wide variety of Cameras for every application - from student to professional use:

Select a type of camera - Eyepiece, USB 2.0 or USB 3.0 - to name the most popular choices

Choose the Megapixels of the camera - the higher the megapixel count on a camera sensor the greater the amount of detail that can be captured in an image

The Higher the Magnification - The More Detail You'll See

Magnification 40x
Magnification 1000x
Magnification 2500x

Magnification is the ability of your microscope to make small objects seem larger. As the magnification increases the area being viewed will be decrease is size but the detail of the area being viewed will improve.

Amscope microscopes come with multiple magnifications to aid you in finding the proper magnification for viewing each specimen.

Camera Connection Types

When comparing 2.0 and 3.0 there are few major differences. First the transfer rates. USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster.

Camera Resolution

The most important factor in ensuring successful microscopic imaging is choosing the appropriate optics and camera for your application that gives you more data and higher image quality. When selecting a microscope camera, it is best to base your decision on the most important requirements for your microscopic observation.

Key Features

  • 40X to 2000X magnification range using high-quality plan-achromatic objective lenses. 10X and 20X eyepieces provide 8 unique magnification settings.
  • An epi-fluorescence microscope for laboratories and universities using wide-spectrum 100W mercury HBO arc-lamp and two filter blocks for blue and green band excitation
  • The infinity-corrected optical system reduces distortion and improves color accuracy.
  • Plan-achromatic lenses produce high-contrast images with edge-to-edge sharpness.
  • The Koehler illumination system provides centered, evenly-distributed lighting with a field aperture for maximum contrast and definition.

The FM690B adds epi-fluorescence to our popular 690 series laboratory microscopes, with a wide-spectrum mercury arc-lamp and two standard filter blocks for blue and green excitation bands. This provides high-contrast imaging of fluorescing compounds by isolating bands of light through multi-stage filtering. The microscope's infinity-corrected optical system ensures reliable, low-distortion magnification, with plan-achromatic corrections for accurate colors, excellent field flatness and edge-to-edge sharpness. The halogen illumination system provides low-fatigue, evenly-distributed light for maximum contrast and definition. This model is a popular choice for veterinarians and university laboratories.

The binocular head can be rotated 360° to accommodate viewing from various angles. The binocular viewing tubes are set to a 30° incline and use Siedentopf adjustment to provide a high level of comfort.

The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 20X eyepieces expand the maximum magnification to 2000X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, soil, and bacteria. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are achromatically corrected to improve resolution and color accuracy, with planatic flat-field correction to provide edge-to-edge sharpness.

The large 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.

Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The halogen light-source provides bright illumination with a lower color-temperature for decreased fatigue when used for long periods. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

Fluorescence

The epi-fluorescence illumination system adds incredible versatility to the microscope. The ability to isolate fluorescing compounds allows you to target individual proteins and other nuances. The illuminator uses a high-power mercury arc-lamp for wide-spectrum excitation, with two filter blocks for blue and green excitation, covering a wide range of popular labeling agents and natural fluorophores.
